Though natural cycles and fluctuations have caused the earth's climate to change several times over the last 800,000 years, our current era of global warming is directly attributable to human activity—specifically to our burning of fossil fuels such as coal, oil, gasoline, and natural gas, which results in the ...
As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the 'greenhouse effect.
That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases.
The ocean has a huge impact on climate, so NOAA monitors ocean conditions with satellites, ships, and buoys. Over 4,000 buoys and floats take daily measurements at the ocean surface as well as thousands of feet below.
Greenhouse gases The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.

Carbon dioxide (CO2)Global Warming Potential (100-year): 1 Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities.
Greenhouse gases are gases that can trap heat. They get their name from greenhouses. A greenhouse is full of windows that let in sunlight. That sunlight creates warmth.
Nitrous oxide is emitted from wastewater that contains nitrogen-based organic materials, such as those found in human or animal waste. Factors that influence the amount of nitrous oxide generated from wastewater include temperature, acidity, biochemical oxygen demand, and nitrogen concentration.
The World Meteorological Organisation (WMO) performs a vital role in this respect. The National Meteorological or Hydrometeorological Services (NMHS) of 189 member states and territories form the membership of the WMO.
Modern observations mostly come from weather stations, weather balloons, radars, ships and buoys, and satellites. A surprisingly large number of U.S. measurements are still made by volunteer weather watchers.
Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth's surface and extends from 4 to 12 miles (6 to 20 km) high.
